Number the letters of the alphabet A-Z, 1 to 26 respectively, then delete the letter 'X'. Using the information given, place the remaining 25 letters into the diagram. Three letters are already in place.

The totals next to the columns, rows and diagonal lines, are the total value of the letters to be placed in the column, row or diagonal line. The value of the letters U and F are 21 and 6, therefore the value of the remaining letters in the centre column is 22.

The letter S should be placed in a square diagonally adjacent to the square containing the letter O.

The centre column should contain three vowels.

Place the letters Z, H and T in the same column.

Place the letters G, H and I in the same row as the letter W.

Place the letter M in the same column as the letters as the letters W and Y, and in the same row as the letters E and F.

Place two vowels in the top row, but do not place any vowels in the second row from the top.
